Ducted Mini Splits vs. Traditional HVAC Systems: Which is Right for You?

We don’t realize how important heating and cooling are to our home until we’re without it – which is never a pleasant circumstance in Washington! When it comes to maintaining the perfect climate control, choosing the right system is essential to maintaining comfort and energy efficiency throughout the year. Homeowners and business owners are faced with various choices to meet their specific needs – the seemingly endless options can be overwhelming! Over the past few years, one system that has garnered significant attention is the ducted mini split system, an energy-efficient alternative to traditional HVAC systems. At Apollo Heating & Air, we’ve worked extensively with both systems and see firsthand how each can provide comfort in different settings. Today, we’ll take a deep dive into ducted mini splits and traditional HVAC systems to help you decide the best option for your space.

Understanding the Basicsbasics of HVAC systems

Before diving into the comparison, it’s essential to clearly understand both systems and how they each work. 

What is a Traditional HVAC System?

Traditional HVAC systems, often referred to as central heating and cooling systems, have been the standard for residential and commercial heating and cooling for many years. These systems rely on a network of ducts to distribute conditioned air throughout a building. Central HVAC systems typically include an indoor furnace or heat pump for heating and an outdoor air conditioning unit for cooling. These systems are designed to provide whole-home heating and cooling, offering comfort across every room. In addition to their ability to heat and cool large spaces efficiently, traditional HVAC systems also benefit from existing ductwork, which makes retrofitting easier in many homes, saving on installation time and cost compared to systems that require new ducting.

What is a Ducted Mini Split System?

A ducted mini split system is a type of heating and cooling solution that combines the efficiency of a ductless mini split with the flexibility of ductwork like a traditional HVAC system. The system consists of an indoor air handling unit connected to a network of ducts that distribute conditioned air throughout your home or business. A ducted mini split system works similarly to traditional HVAC systems, with multiple indoor air handlers connected to a central outdoor unit. The primary benefit of ducted mini splits is their ability to provide zoned heating and cooling, allowing different areas of the home or building to be conditioned independently. This allows for more precise temperature control and reduced energy consumption, as you only need to heat or cool the areas that are in use.

Benefits of a Ducted System Compared to Ductless Mini Splits

While ductless mini splits are known for their efficiency and flexibility, ducted mini splits offer additional advantages. One of the key advantages of a ducted mini split system is its ability to serve as a whole-home or whole-building solution rather than a unit that provides air to a single room or area. This makes it an excellent option for larger homes or commercial properties that require consistent climate control across multiple rooms. Additionally, the ducted system can be easily integrated into existing homes with central heating systems with existing ductwork, allowing for seamless installation.

Key Differences Between Ducted Mini Splits and Traditional HVAC Systems

Now that we understand the basics of each system, let’s compare the two across some critical factors: energy efficiency, installation process, space considerations, maintenance, and heating and cooling performance.

1. Energy Efficiency: Which System Saves More on Utility Costs?ducted mini splits and traditional HVAC system

One of the biggest selling points of ducted mini splits is their energy efficiency. These systems use inverter-driven technology, which allows the unit to adjust its speed and output based on the demand for heating or cooling. This results in significantly less energy consumption compared to traditional HVAC systems, which often use fixed-speed compressors that run at full capacity even when the demand for heating or cooling is low.

While technological innovations have made traditional HVAC systems more energy efficient than in the past, they are typically less efficient than mini splits. This is due to their lesser zoning capabilities, inferior targeted heating and cooling capacity, and the fact that they often run at full power. Additionally, many mini split units also utilize heat pump technologies, transferring heat instead of generating it, making them more efficient and earning higher SEER ratings. 

2. Installation Process & Cost: Comparing Installation Complexity and Expenses

When considering installing a new HVAC system, costs and complexity are two essential factors to keep in mind. Both ducted mini split systems and traditional HVAC systems are good choices in homes with existing ductwork and can be easier and less expensive to install and replace. If your home already has ducts in place, upgrading to a new central heating and cooling system can be a relatively smooth process, provided the ductwork is in good condition. Depending on your previous system, you should consult a heating and cooling professional like Apollo Heating and Air Conditioning to see if your ductwork would require modifications for your new system. 

In contrast, installing either a ducted mini split system or traditional HVAC in a ductless space can be more costly upfront due to the need for custom ductwork installation. The complexity of installation can vary depending on the layout of your home or business, but it may involve modifications to walls, ceilings, or floors to accommodate the ducting. However, both of these systems face challenges without proper installation – poorly installed systems compromise energy efficiency. 

3. Space Considerations: Which System is Better for Smaller Homes, Older Homes, or Large Properties?

When it comes to space, each system offers distinct advantages depending on the setting and your preferences. Ducted mini splits can be an excellent choice for both older homes and new construction, giving good quality existing ductwork. The system’s flexibility allows for efficient zoning, meaning smaller homes or individual rooms can be easily conditioned, and larger homes can be zoned into different temperatures without wasting energy on unused spaces.

Traditional HVAC systems are ideal for larger homes with existing ducts, as they can easily cover the entire space and provide even heating and cooling. These systems are designed to serve multiple rooms, making them an efficient choice for large homes or businesses looking to maintain a consistent temperature throughout the space. However, in older homes without existing or poorly maintained ducts, the installation process may be more invasive and expensive.

4. Maintenance Requirements: Long-Term Upkeep, Repairs, and Servicing Differencesducted mini splits system

Maintenance is an important consideration for both ducted mini splits and traditional HVAC systems. Both systems require regular maintenance to ensure they continue to perform efficiently, including cleaning or replacing filters, checking refrigerant levels, and ensuring the ducts remain unobstructed and clear from accumulated dust, debris, and mold. 

Ducted mini splits have a more straightforward design and tend to require fewer repairs than traditional HVAC systems, especially when ductwork is in good condition; however, they require more frequent filter changes. Traditional HVAC systems require more maintenance, as they are typically composed of several more complicated components. In traditional HVAC, the furnace, air handler, and air conditioning units need to be serviced to keep them running smoothly, which can result in higher maintenance costs over time, especially for older systems.

5. Heating & Cooling Performance: How Each System Performs in Different Climates

Both ducted mini splits and traditional HVAC systems perform well in a variety of climates, but each has its own advantages. Ducted mini splits are highly effective in both heating and cooling, thanks to their inverter-driven compressors and precise temperature control. In colder climates, some models come with built-in heaters that can provide efficient heating even in freezing temperatures. They also work well in moderate climates, offering effective cooling without large fluctuations in energy use.

Traditional HVAC systems perform reliably in most climates, but their efficiency can be compromised in extremely hot or cold regions. These systems tend to experience more energy loss, making it harder to maintain consistent temperatures in high or low temperatures. However, traditional HVAC systems are still a good option for large spaces where consistent temperatures across multiple rooms are needed; the energy will likely just come at a higher price.
